Orion's solopreneur tools roundup ranks what he actually uses to run a one-person operation. For a solo digital seller on Gumroad + Stripe, the bottleneck isn't more AI apps — it's knowing net profit after fees and what to set aside before quarter-end.
SellerLedger on Gumroad is Orion's $17 Google Sheet that imports both CSVs. His tax guide walks the five-tab structure free. This post clones his listicle shape for the seller-finance stack only — same honest "what free actually means" framing.
Not tax advice. Talk to a qualified tax professional in your country.
What "free" actually means for sellers
Most seller tools are either:
- Genuinely free (CSV exports, Google Sheets, open-source CLIs)
- Free until you sell (Gumroad/Stripe take % per transaction)
- One-time purchase (SellerLedger $17, or a EUR 9 CLI pack)
I'll call out real limits. None of these need a monthly SaaS subscription to start.
1. Gumroad — checkout + file delivery
Cost: 10% per sale, no monthly fee.
Best for: First digital product, instant purchasable link.
Honest limit: Weak discovery — you drive traffic (dev.to, landing page). Non-negotiable for Product 1.
2. Stripe — payouts that never match Gumroad gross
Cost: Per-transaction fee only.
Best for: Direct sales, subscriptions, Gumroad payout deposits.
Honest limit: Dashboard shows gross; your accountant wants categorized rows. Export CSV monthly.
3. CSV export habit — the boring free tool
Cost: €0.
Best for: Monthly reconciliation before quarter-end panic.
Gumroad → Customers → Export. Stripe → Payments → Export. Five minutes monthly beats a weekend reconstruction.
4. SellerLedger ($17) or EUR 9 CSV ledger CLI
What it is: SellerLedger auto-imports both CSVs into a five-tab P&L with tax set-aside estimate. Orion's build log explains why Product 4 exists.
Free alternative — run locally, CSV never leaves your machine:
python3 seller_ledger.py gumroad-sample.csv stripe-sample.csv -o ledger.csv --tax-rate 0.28
Stdout prints gross revenue, platform fees, net profit, and set-aside estimate.

5. Google Sheets — accountant handoff
Cost: €0.
Import ledger.csv or use SellerLedger's template. One categorized file beats platform screenshots.
6. dev.to — free distribution rail
Cost: €0.
Orion posts seller-finance guides here and links Gumroad CTAs. Same shape: teach the problem, link the paid sheet or CLI.
